摘要

为研究斜齿轮传动系统的动力学特性,根据单级斜齿轮副传动情况,建立考虑齿面时变摩擦的5自由度弯—扭—轴耦合传动系统动力学模型。依据重合度对啮合时间进行划分,由Buckingham半经验公式得到齿面摩擦因数随啮合点位置的变化规律。采用变步长Runge-kutta法对系统运动微分方程组进行数值求解,得到系统分岔图、最大Lyapunov指数、最大幅值云图和幅频特性叠加图,分析系统随激励变化的动力学特性。研究发现,系统在特定参数下发生强共振响应及幅值跳跃现象。

Abstract

In order to study the dynamics characteristic of the helical gear,according to the situation of helical gear pair in the process transmission,a 5- degree bending- torsion- shaft coupled dynamics model of single- stage helical gear transmission system is established with time- vary friction force. According to the influence of contact ratio,the meshing time is divided. Based on Buckingham semi- empirical formula,the tooth surface friction coefficient variation with the meshing- point position is obtained. The movement differential equations are discussed by the variable step size Runge- Kutta method. The bifurcation diagrams,Lyapunov exponents,cloud pictures of the maximum amplitude and the amplitude- frequency characteristic superposition graphs are obtained and the system dynamics characteristic variation with frequency is analyzed. The strong resonance and amplitude jump phenomenon are happened under the conditions of a particular parameter.
